Is Hydra good for hiking?
Yes, Hydra is excellent for hiking.
Few places in Greece are as rewarding for walkers as Hydra. Wheeled vehicles are forbidden across the whole island. There is no traffic to contend with and no engine noise to break the quiet. The only transport is on foot, by donkey or by boat. This unique car-free character means that the moment you leave the harbour. You step onto a network of ancient paths that have carried people and mules for centuries, winding up into the hills and out along the coast in perfect peace.
The terrain is dramatic and varied, giving hikes for every level of walker. Steep, rocky mountainsides clothed in pine rise straight from the sea, cut by valleys and dotted with chapels, monasteries and the ruins of old estates. Trails lead to secluded swimming coves, to mountain monasteries with panoramic views, and to the bare summit of the island’s highest peak. From gentle coastal ambles to lung-testing climbs, the range is wide, and the scenery is superb throughout.
Most walks can be completed in half a day or less, making it easy to combine a morning hike with an afternoon swim or a leisurely lunch back in town. The paths are among the best-maintained on any Greek island. Most of them beautifully paved in stone. The network is dense enough that you can walk a different route every day of a stay. For walkers, hiking in Hydra is not just possible but a genuine highlight of the island.
What are the best hiking trails on Hydra?
The best hiking trails on Hydra are the coastal path from Kamini to Vlychos and Agios Nikolaos, the stone-paved climb to the monasteries of Profitis Ilias and Agia Efpraxia, the ascent of Mount Eros, and the long remote trail east.
Hydra has a handful of classic routes that between them capture the best of the island’s walking. Along the coast, the path west from the town through the little harbour of Kamini to Vlychos and on to the beaches beyond is the most popular and one of the loveliest. A fairly easy walk with the sea always at your side. It is the natural first hike for most visitors and can be as short or as long as you like. Turning back whenever you find a cove you want to swim in.
For those who want to climb, the stone-paved path up to the monasteries of Profitis Ilias and Agia Efpraxia is the great half-day walk. Zigzagging through pine forest to a pair of working religious houses high on the mountain. Fitter and more ambitious walkers can push on and up to the summit of Mount Eros, the highest point in the Saronic Gulf, for the widest views on the island. Each of these routes offers something different, from shady forest to open ridge.
The most demanding of the well-known walks is the long trail east to the remote monastery of Zourvas. Near the far tip of the island, a full day out through wild, empty country far from the town. Between these headline routes run shorter link paths, so you can mix and match: a coastal stroll one morning, a monastery climb the next. Together they make a varied menu of the best hiking on Hydra, from the easiest seaside walk to a serious mountain day.
How do you hike the coastal path from Kamini to Vlychos?
The coastal path from Kamini to Vlychos is an easy, mostly level walk of about half an hour each way, following the shore west from Hydra town through the fishing harbour of Kamini to the pebble beach and old stone.
The Kamini to Vlychos walk is the gentlest and most popular hike on Hydra, and the perfect introduction to the island on foot. Starting from the western edge of the town, the path hugs the coast. Passing grand old sea captains’ mansions before reaching the small fishing harbour of Kamini, with its bobbing boats and a couple of tavernas. From here the route continues along the shore, sometimes on a paved path and sometimes on a track. With the clear water lapping the rocks just below you all the way.
A pretty hamlet with a pebble beach, a scattering of houses and an old arched stone bridge that is one of the island’s landmarks. The pebbled cove here, and the nearby beach at Plakes, are lovely places to swim and cool off, and there are tavernas for lunch by the water. Many walkers time the outing so they arrive hot and ready for a dip, then rest over a long lunch before strolling back.
The path can be extended beyond Vlychos toward the quieter beaches and coves further west. Or shortened simply by turning back whenever you please, which makes it suitable for families and casual walkers. Being low and coastal it is walkable across three seasons, though it offers little shade, so it is best in the cooler hours. This seaside route is also the easiest way to reach the island’s finest beaches on foot.
What is the walk to the monasteries and Mount Eros?
The walk up to Hydra’s monasteries climbs a stone path from the town to Profitis Ilias and Agia Efpraxia in about an hour to ninety minutes.
The climb into the mountains above the town is Hydra’s classic uphill hike. A stone-paved path zigzags up through the pines from the edge of the settlement, gaining height steadily until, after an hour to ninety minutes, it reaches the monastery of Profitis Ilias and the neighbouring convent of Agia Efpraxia. These working religious houses, set high on the slope with sweeping views over the town and sea. Are the goal for most walkers. The shady, well-built path makes the ascent a pleasure despite the climb.
The full story of this route, the monasteries themselves and their history is covered in our guide to the monasteries of Hydra, but as a hike it stands among the best on the island: a real climb with a rewarding destination and one of the finest panoramas in the Saronic Gulf. Modest dress is needed to enter the monasteries, and it is worth timing your arrival for their morning opening hours, before they close for the middle of the day.
Strong walkers with energy to spare can continue beyond the monasteries onto the bare upper slopes and up to the summit of Mount Eros. At 588 metres it is the highest peak in the whole Saronic Gulf. The reward is a truly vast. All-round view taking in the island, the surrounding sea and the mountains of the Peloponnese across the water. This upper section is steep, rocky and exposed, with no shade, so it is only for the fit and well prepared, but the summit view is the grandest on Hydra.
Can you hike to Zourvas and the remote east of Hydra?
Yes, a long, demanding trail runs east from the town to the remote monastery of Zourvas near the island’s far tip, a full-day hike of three to four hours each way through wild, empty country.
For serious walkers, the great expedition on Hydra is the trek east to Zourvas, the isolated monastery near the far eastern end of the island. The trail leads away from the town and its familiar coastal paths into the wild, sparsely inhabited interior and eastern shore. A landscape of bare hills, scattered chapels and long sea views with barely a building in sight. It is a full day’s undertaking, three to four hours of walking each way. There are no facilities along the route, so it must be treated as a proper mountain hike.
The rewards match the effort. This is Hydra at its most remote and untouched, a side of the island scarcely any visitors ever see. Ending at a beautiful and solitary monastery perched near the sea at the island’s tip. The sense of wildness and space is complete, and the walking, though long, is deeply satisfying for those who enjoy getting well off the beaten track. Reliable navigation, ample food and water, and an early start are all essential for the round trip.
Many hikers arrange to come back from Zourvas by boat or water taxi, turning the day into a one-way traverse of the island. This makes a notable combination, walking out through the wild east and sailing home along the coast, and it removes the strain of retracing the whole route on tired legs. However you do it, the Zourvas trail is the ultimate hike on Hydra and a memorable adventure for experienced walkers.

Framed between the pines on the coastal walks and spread out far below on the mountain climbs. This ever-present sea, set against the green and grey of the land, gives the island’s hikes their distinctive beauty.

On the coastal walk to Kamini you pass the imposing stone mansions built by Hydra’s sea captains and merchants in the island’s golden age. Their proud facades looking out over the water. Scattered across the hills stand countless small white chapels, some no bigger than a shed. Along with the crumbling walls of old farmsteads, cisterns and threshing floors that tell of a busier rural past. Every walk becomes a quiet journey through the island’s story as much as its landscape.
Nature adds its own rewards. In spring the hillsides come alive with wild flowers, from scarlet poppies to purple thyme and yellow broom. The air hums with bees and birdsong, while the resident donkeys and mules that do the island’s carrying are a charming sight along the paths. Lizards dart over the warm stones, hawks wheel above the ridges, and the clear light picks out the colours of rock, sea and sky.

Well equipped, hiking in Hydra is a safe, simple pleasure and one of the very best ways to experience the island.
